}Create a BootstrapRequest
Open one agent-native onboarding attempt (Plan 901). Takes the pinned Starter identity, the CLI’s client challenge and ephemeral encryption public key, and a safe project fingerprint; returns the bootstrap id, activation URI, short user code, and the once-issued poll token. The user code and poll token exist exactly once — the create response is their only delivery, and the stored record carries digests only. This route serves the deliberately narrow pre-authentication CLI audience and is rollout-fenced: the deployment’s BOOTSTRAP_REQUESTS_SURFACE fence must be enabled or the request is denied.
Checkfu support posture: preview; rollout_fenced. No release evidence journey applies to this operation.
